Friction-based control system for seismic energy dissipation with isolated stories
… in structures to increase the performance under seismic and/or wind loading either by adding stiffness or inducing counteracting forces which dissipate energy in various ways. In order to efficiently dissipate the seismic energy with existing schemes, large structural displacements are required. …

Evaluating Shear links for Use in Seismic Structural Fuses
… behavior including increased stiffness and energy dissipating ability. Both of these characteristics lead to reduced drifts during earthquakes, which in turn leads to a reduction of drift related structural and nonstructural damage. Shear links are being used for seismic energy dissipation …

Computational and Experimental Investigation of Seismic Structural Fuse Shapes for Structural Systems
… damage, and then be replaceable after a major seismic event. A promising type of seismic structural fuse consists of a steel plate with engineered cutouts leaving a configuration of shear-acting links remaining. There have been several studies on various cutout patterns for shear-acting …

Development of Electromagnetic Friction Dampers for Improving Seismic Performance of Civil Structures
<p>Energy dissipation is critical to limiting damage to civil structures subjected to extreme natural events such as earthquakes. Friction is one of the most reliable mechanisms of energy dissipation that has been utilized extensively in friction dampers to improve seismic performance of civil …

Topology Optimization of Steel Shear Fuses to Resist Buckling
… events such as earthquakes, that dissipate energy through localized shear or flexural yielding mechanisms. Although previous studies have reported that fuses with specific geometry can develop a stable hysteretic behavior, their small thickness makes them prone to buckling, reducing strength …

A Framework for Cyclic Simulation of Thin-Walled Cold-Formed Steel Members in Structural Systems
… is to create a computationally efficient seismic analysis framework for cold-formed steel (CFS) framed-buildings supported by hysteretic nonlinear models for CFS members and screw-fastened connections. Design of CFS structures subjected to lateral seismic forces traditionally relies on the …
